The roughness tester PCE-RT 2300 is used to measure the roughness of surfaces. The PCE-RT 2300 roughness meter has a removable motorized sensor. This property makes it possible to determine the surface roughness with the roughness tester even on small or narrow profiles. The measured values ​​are displayed on a large LCD display of the roughness meter. This display is also used by the roughness tester. The roughness tester is powered by an internal battery with voltage. This battery can be powered by a conventional USB power adapter.

The detachable motorized sensor is connected by a cable to the main unit of the roughness gauge. The diamond stylus is installed in the motorized sensor. This presses with a maximum force of 4 mN on the surface from which the roughness is to be measured. The roughness tester measures according to the valid ISO, ANSI and JIS standards for roughness measuring instruments.

Worth knowing about the roughness measuring device:

Rz = average roughness
The mean roughness depth Rz is the arithmetic mean of the largest individual seam depths of several adjoining individual measuring sections.

Ra = arithmetic mean roughness
Ra is the generally recognized and internationally applied roughness parameter. It is the arithmetic mean of the absolute values ​​of the profile deviations within the reference line. The measured value Ra is always smaller than the Rz value determined on the same roughness profile.

Rt = maximum roughness
The maximum surface roughness Rt is the distance between the highest and the lowest point of the measuring section.

Rq = Square Mean Roughness
Rq is the root mean square of all ordinate values ​​within the individual measurement distance l. Rq corresponds to the designation RMS (Root Mean Square).
